THE HOLLEY HERITAGE
It was more than 100 years
ago that brothers George and
Earl Holley began building
and racing motorcycles in
rural Pennsylvania. By 1897,
they had designed and built
their first automobile, a
three-wheeled, single-cylinder
vehicle which reached an
impressive speed of 30 miles
per hour. Two years later,
they formed the Holley Motor
Company. In 1903, at the urging of Henry Ford, the Holley brothers
entered the carburetor business and became industry leaders in fuel
system technology. And the rest, is history.
As Holley heads into the
new millenium, the
Heart and Soul of
Performance beats
even stronger with
a strengthened
market focus and a
total awareness of its role
as the performance industry
leader. Leadership brings on
responsibility and not the least of this
involves an extreme dedication to provide
Holley customers with performance products
that will enable them to stay ahead of the competition.
Holley has fulfilled this role, and you can be assured that it
will continue to do so in the future.
The story of Holley, however, does not end there. Over the years
much has been accomplished and much has changed. Today, Holley
Performance Products is the leading company in the performance
aftermarket. From the entry of air into the air cleaner through its
exit out the exhaust, Holley products ingest, control, compress, ignite
and enhance the properties of fuel and air to the point where the
result is impressive horsepower.
Starting with 1997, Holley began adding complementary performance
products to bolster its extensive line of fuel system products.
ANNIHILATOR ignition was introduced. Announcements about the
buy-outs of Weiand and Lunati, followed in quick succession. The
following year Hooker Headers and the supercharger line of B&M
Performance were added. The trend continued, and late in 1999
FlowTech exhaust, NOS and Earl’s plumbing were brought into the
fold. With these additional product lines, Holley is THE premier
performance company, offering the most significant and diversified
product lines.

INTRODUCTION
THE HOLLEY ENGINEERING CENTER
The 14,000 square foot Holley engineering center in Bowling
Green, Kentucky is a state-of-the-art facility with the latest
equipment and the largest staff of graduate engineers in the
performance industry. Their sole job is to invent new products
so that you can go faster.
The idea for many new products begins when someone at a
race or show, or on a sales call, walks up to a Holley
representative and questions why we don’t make a certain
product. We take these suggestions and work with our
engineers to create the performance and race products of
your dreams.
Other ideas for new products spring directly from the minds of our engineers who share the Holley passion for speed. They
constantly study our current and competitors’ products, looking for new ways to improve product quality and performance.
The Holley Engineering Department is organized into five
teams: air management, engine management, fuel manage ment, electronics and exhaust. We also have partnerships
with independent experts like Keith Dorton, John Lingenfelter,
Pat Musi and Sean Hyland to extend our new product
development capabilities even further.
Within Holley Engineering is a Design and Development
Department. In this department, Holley engineers use the
latest ProE 3-D Computer Aided Design (CAD) technology. The Design Department has 12 advanced, ProE workstations,
more than anyone else in the performance industry. The ProE 3-D system allows the engineer to build a threedimensional model of a proposed part on his computer. The system considers mass properties as well as dimensions.
Parts can be assembled in this virtual environment and manipulated to check clearances within the intended mounting
area. When the design is completed, the ProE system provides a digital image from which a prototype part can be built
in just a few days’ time. Once built, new product prototypes can go directly to the Development Department, to be tested
under simulated and actual-use conditions. They can be tested either on sophisticated test fixtures or bolted directly to
engines or performance vehicles.
The Holley Development Department has four engine
dynamometers that are fully programmable, including one that
goes up to 2,000 horsepower, and three chassis dynamometers.
Because of the scope of our rigorous product testing and devel opment schedule, we had designed dedicated dynamometers
that were built to our own unique specifications.
Dynamometers permit precise measurement of component
performance at specific engine RPM or wheel speeds.
For example, our 1,000 horsepower chassis dynamometer has
been upgraded to test steady state load systems, designed to
hold at a fixed speed and throttle setting. Our chassis
dynamometers can accept a wide variety of vehicles including
motorcycles, ATVs and go-karts.
4
The Development Center also has complete emissions
testing capability to perform full FTP 75, drive cycle
testing, to strict OEM requirements. The Holley
Development Department also has salt spray and high
temperature test chambers, the largest wet-flow bench
in the world and other state-of-the-art equipment for
measuring airflow and fluid usage. Various electronics
testing devices and durability test stands round out the
specialized product testing capabilities that are
available in this center.
You may have had occasion to hear about the show cars
Holley has built for its centennial celebration. These
cars are based at the Holley Engineering Center and are
part of our active test fleet, which now includes over 20
high performance vehicles. For road tests we have our
own small track on the premises as well as a contract
with a nearby drag strip and oval track. At Holley,
every new product is thoroughly tested before it is
released for sale. Our new digital fuel injection system,
for example, was tested for over 100,000 miles.
Our all-new exhaust system design and manufacturing
facility in Aberdeen, MS gives us total capability to
design headers, cat-back systems and full-length,
free-flow exhaust systems for vehicles from muscle cars
to motorcycles. This facility is fully integrated into
Holley engineering’s ProE 3-D CAD design system, and
gives Holley a capability that is second to none in the
industry.
The Holley Engineering Center is located at the Holley
corporate headquarters in Bowling Green, KY.
Tours are available. For more information,

INTRODUCTION
That used 23’ Formula you
bought looks great lying
there in the boat well,
gently tugging at the
mooring lines. It’s got a
350 Chevy engine that
you think will be just
the ticket for fast runs
across the lake. The old
4-bolt main block has a
lot of hours on it, but you
figure that a fresh rebuild over
the winter months will bring it back
up to snuff. You’d like it to be able to hit 60
M.P.H. Obviously, some changes will be in order; a high-rise manifold
and a 750 CFM carburetor for starts. Probably a bit more radical
camshaft to make that transom exhaust sound real sweet. If Santa’s
really good to you, maybe a supercharger kit. Now that’d be nice.
Problem is, where do you begin looking for the parts? Marine stuff is
special, so you’ve got to be careful what you buy. You’ve got the plan,
where and how do you start?
You’ve had some good times with your 36’ convertible sedan.
The twin big blocks, however, are getting a little tired after 10 seasons of
great fishing and cruising. The two-week summer cruise you took up
North this year, though, took more fuel than usual. The after-cruise
check up revealed that cylinder compression is down in both engines.
Regular and routine maintenance has shown that oil consumption is up.
The starboard engine also needs a carburetor rebuild. It’s been getting
hard to start when cold and doesn’t seem to idle as well as it once did.
It also now has a tendency to stall at idle when warm. This sometimes
makes for some interesting dockside maneuvers. All in all, though, she’s
been a good boat and the layout has been just great for the family.
She’s like having a second home. The boating season is fast coming to
an end and soon you’ll have to haul out for winter storage. This might
be a good time to start thinking of freshening up the engines. Sounds
like a good idea but where and how do you start?
How indeed do you start?
Start by looking at Holley’s line of marine products. Holley products can
enhance the quality of your cruising life-style. Whether your time is
spent doing poker runs in an offshore racer or maybe just cruising up a
lazy river in a comfortable cruiser or houseboat, you want assurance that
the equipment used is safe, reliable and will perform flawlessly. You
want products that will give you and your family the confidence
to venture out on the waters in
and around your cruising
area.
Holley has been manu facturing marine prod ucts for years and you’ll
find them used on
engines that are marinized
8
by such noted companies as OMC, Volvo-Penta, Crusader, Pleasure Craft, Marine Power, Mercury and
Indmar. These are in addition to original equipment marine engines from Ford and General
Motors. This long-time original equipment marine experience has enabled Holley to
build up an impressive array of marine products such as carburetors, fuel injec tion systems, intake manifolds, fuel pumps, ignition systems, supercharger kits
and camshafts.
Original equipment replacement, performance and race marine
carburetors are all available through Holley. Whether it’s
replacing that old Rochester Quadra-Jet with a new Holley
marine spread bore or installing dual 750s on a newly built
supercharged engine with all the chrome and polished goodies,
Holley has a marine carburetor for you. Holley is the only
manufacturer to offer such a diverse marine carburetor line that
can address the needs of drag boats using 4500 DOMINATORS to
pleasure boats equipped with a standard
two-barrel or four-barrel carburetor.
With the addition of Weiand, Lunati and Hooker to the Holley family, the marine product list
is now more extensive than ever. For those who take their poker runs seriously, Holley has
available a wide range of Weiand superchargers for the small block and big block
Chevrolet V-8 engines. If you have a fresh-water-cooled engine or run in fresh water,
there’s a Weiand or Holley aluminum intake manifold just for you. Intake manifold
designs are available for engines that make power in the low end, mid-range or high
RPM. These products, coupled with available Lunati camshaft kits and Holley performance marine
carburetors and fuel pumps, will enable you to hop waves and jump wakes with the best of them.
Marine electronic fuel injection systems are also available for those who want the latest in
fuel delivery technology. Holley gives you the choice of three system designs, Pro-Jection
2-bbl TBI, Commander 950 4-bbl TBI or Commander 950 MPI. Pro-Jection is a line of
universal throttle body systems that can be used on either stock, unmodified engines or
on modified engines rated up to 275 horsepower. These systems can be used with a
factory-stock two-barrel or four-barrel manifold or with an aftermarket manifold.
They’re complete systems and are designed to replace the original equipment carbure tor. A move up the fuel injection scale is the Holley Commander 950. Available either as
universal 4-bbl TBI systems or as a true multi-port for Chevrolet V8 engines, Commander 950 is
the most powerful engine controller available today. These are complete systems that are engineered to replace the original
equipment carburetor, manifold and fuel pump. Included is a special intake manifold with injectors and all necessary fuel lines
and hardware. This is top quality stuff with looks that will make your boat the envy of the marina.
Marine ignition systems receive a major assist from Holley ANNIHILATOR ignition. ANNIHILATOR ignitions are microprocessorcontrolled, capacitive discharge systems with the added benefit of having a multiple spark feature. The basic “HP” system features
a single rev limiter that is adjustable in 100 RPM increments from 1000 to 9000 RPM. The “STRIP” system features three rev
limiters, two RPM switches, timing retard on start-up and crank trigger capability. It also includes the unique QUICKSHOT
Programmer that allows you to remotely adjust all settings of the system. The ProStrip system has four rev limiters and RPM
switches, the QUICKSHOT Programmer and a fully-programmable timing computer. It also features timing retard, boost retard
and an emergency kill/alarm. This is just the ticket for a maxed-out offshore cruiser or lake blaster. They all meet
Coast Guard requirements. ANNIHILATOR ignition modules are completely sealed (potted) from the environ ment so corrosion will not be a problem. All connectors are top quality. ANNIHILATOR ignition
systems were originally designed for racers where vibration problems are EXTREME and perfor mance and durability are an absolute MUST. They will stand up to the harshest marine
environment while delivering reliable multiple spark combustion performance.
So, if your cruising seems to have lost its edge and the excite ment of doing the fast runs across the lake is gone, it’s
time to inject some new life into your tired motor(s)
with Holley marine performance products.

FUEL SYSTEMS
Marine Carburetor Descriptions
If it looks like a duck and quacks like a duck, it must be a duck.
Right? Well, maybe. Carburetors are carburetors, but only marine
carburetors should be used on boats. It’s true that marine carbu retors started life as regular automotive carburetors but then each
took divergent paths.
Marine carburetors have certain modifications that make them
uniquely adaptable and legal for marine usage. “Legal” meaning
that it has the ability to pass the U.S. Coast Guard test for marine
carburetors. Folks, I’m not talking about Paris Island here, either.
The main qualification that a marine carburetor must meet (as set
down by the U.S. Coast Guard) is that if the carburetor should
“flood” only .5cc of fuel is allowed to escape in a period of 30
seconds. There’s also a “backfire” test which confirms the ability
of carburetor/flame arrestor combination to contain the backfire.
For this reason a gasket is not used between the carburetor airhorn
flange and the flame arrestor. It’s possible that this gasket could
become saturated with fuel (if the carburetor should flood) and
become a potential fire source as a result.
The primary areas of a carburetor that require some sort of modifi cation to meet these requirements include the fuel bowl vent tubes
and throttle shafts. The vent tubes of a marine carburetor are
bent inwards so that the tube looks like an inverted “J”. These
tubes oftentimes are referred to as “J” tubes, as a result. The
reason for bending the tubes inward is that if flooding should
occur, the fuel that would normally come out of the fuel bowl vent
tube is rerouted back into the carburetor.
Throttle shafts also get special machining attention. Shafts are
“grooved” and “slabbed” to prevent fuel from exiting out the
throttle shaft if flooding should occur. When a carburetor floods
fuel will end up “puddling” on the throttle plates. A non-marine
carburetor will allow this fuel to seep out of the throttle shaft
ends and onto the manifold. This is not allowed on a marine
carburetor because normally the engine is situated in an enclosed
bilge where potentially deadly gasoline fuel fumes can accumulate.
Throttle shafts that are “grooved” and “slabbed” channel the
flooded fuel safely down into the intake manifold. With no raw
fuel allowed to puddle on the manifold outside the carburetor,
there is no chance of deadly fuel fumes to accumulate in the bilge
and no chance of explosion or fire.
For these reasons an automotive carburetor should NEVER be used
in a marine application.

Performance Carburetors
Square Flange 4 Barrel
Holley marine Performance four
barrel carburetors are available in
both the model 4150 and
4160 styles. Sporting univer sal marine calibrations,
these carburetors are
available in CFMs ranging
from 600 to 850. Depending on
carburetor there’s a choice of
mechanical and vacuum secondaries,
manual and electric chokes and single or dual feed fuel bowls.
Holley marine carburetors use standard Holley parts and special
marine carburetor rebuild kits are available. These carburetors
could be used to replace existing Carter AFB/AVS and Holley
original equipment carburetors. They’re also a good choice for
upgrading, say when changing over from a two barrel to a four
barrel fuel system.
4500 DOMINATOR
The 4500 DOMINATOR marine carburetor
is available only with a racing cali bration. IT’S RECOMMENDED
ONLY FOR ALL-OUT RACING
TYPE ENGINES. The 4500
DOMINATOR uses a special
flange that requires either a spe cial manifold or use of an adapter,
like Holley P/N 17-9. The 7" airhorn
flange also requires use of a special flame arrestor to accommo date this extra large size. This carburetor is unique in other ways
since it does not incorporate a choke nor does it have provision for
one. The bottom line is that this is not your ordinary replacement
carburetor for your family ski boat!
Replacement Carburetors
2300 Flange and Square Flange
Holley marine replacement carburetors are designed as exact
replacements for Holley carburetors that were original equipment
on various late model Ford, OMC and Volvo marine engines. These
carburetors are literally bolt-on replacements for the applications
listed. Throttle, choke and fuel connections should hook right up
without any problem. Holley makes it easy to
regain original equipment response and
power with new marine replacement
carburetors.

IDENTIFYING CARTER AFB
CARBURETOR BOLT PATTERNS
The Carter AFB carburetor was used on many marine installations over the years.
The bolt pattern of the “early” AFBs differ from the later models. When replacing
an AFB carburetor with a new Holley marine replacement carburetor it’s important
to know what you’ve got. The illustrations, at left, will clarify the two different bolt
patterns used on the Carter AFB carburetor.
41/4”
Late AFB
Early Carter AFB Bolt Pattern
When replacing with a Holley model square flange carburetor the following is
required:
• P/N 17-7 adapter
• P/N 717-5 throttle cable bracket (or P/N 17-23 spacer) placed between the
carburetor and adapter to prevent vacuum leaks.
Late AFB Bolt Pattern
This pattern is exactly the same as the Holley models 4150 or 4160, square bore
carburetor. No special adapter is required for this installation.
